Definitions

  • the present invention relates to an elastic support with anisotropic stiffness, in particular for the suspension of vehicle bodies, in particular at the level of the rear axle cross member.
  • the object of the present invention is to solve this problem and, for this purpose, it consists in establishing a support comprising on the one hand a main elastic element intended to support the load and on the other hand means for fixing this elastic element respectively to two assemblies between which the support must be inserted, this support being essentially characterized in that it comprises as main elastic element at least one beam extending in said transverse direction, the ends of this beam being secured to a first frame suitable for being fixed to one of said assemblies and its central part to a second reinforcement suitable for being fixed to the other assembly, and in that the cross section of this beam has a shape such that at the level of said second reinforcement it has the desired stiffnesses, respectively in the longitudinal direction (x-axis) and in the direction of the main load (z-axis).
  • buckling of the beams can be easily avoided by fixing an elastomer block, for example, between the beams of each pair.
  • composition composite materials based on glass fibers, carbon or similar resistant fibers, coated with a polymerized synthetic resin.
  • rods of resistant fibers coated with a polymerized synthetic resin these rods, established in the form of bundles of parallel rods, oriented in the transverse direction, being embedded in a matrix of elastomeric material.
  • This elastomeric material can serve as a shock absorber of the vibrations to which the beams can be subjected, at the same time as a protective envelope protecting the beams from external agents (gravel, humidity).
  • Composite materials are particularly interesting in the intended application, because of their high elongation capacity, but it is also possible to design the same structures with spring steel.
  • the means of fixing the main elastic element which constitute the beam (s) to the assemblies between which the support is to be inserted may be of any suitable constitution, provided that they do not appreciably modify the behavior of the beams. vis-à-vis the efforts and that they ensure a reliable connection, without vibrations, with the reinforcements.
  • the support beam has been referenced 1; it is made of composite material and has centrally a longitudinal and central recess 2, extending between the end legs 3.
  • the main directions in which this beam will have to work have been represented by the axes x, y and z.
  • x represents the longitudinal direction of the vehicle, in which the support must have the lowest stiffness
  • y is the transverse direction (direction of the rear crossmember of the vehicle), in which it must have a very high stiffness
  • z the vertical direction, in which the stiffness must be intermediate. It is essentially the relationship between this latter stiffness and the longitudinal stiffness that the choice of the shape and dimensions of the cross section of the beam will allow to adjust, as indicated above.
  • the beam 1 can, as a first approximation and in the absence of buckling, be considered to have an extremely great stiffness and in any case greater than that which is desired, the stiffness of the support in this direction will depend essentially on the degree the ends of the beam, and it is therefore this which will have to be adjusted.
  • the second frame suitable for being fixed to the vehicle body, by a screw or the like 10, has been reference 11 and may also consist of a metal bracket, covering the middle part of the beam 1.
  • the connection between the latter and the frame 11 can be provided by adhered elastomer blocks 12 and / or by bolting (hole 13). Such bolting can also be used at the ends of the beam, in particular for the case where it would work in traction.
  • FIGS. 1 to 3 the coating of protective elastomer for the beams has not been shown, so as not to make the drawing heavy.
  • each beam 1 has, in plan view, a U shape, with a longitudinal recess centrally 2.
  • the end wings 14 of the beams are used for their anchoring in blocks of elastomer connecting to the reinforcements, namely blocks 4 extremities adhered to the wings 5 of a first metal frame 6, and central blocks 12 adhered between the wings of a metal stirrup 11, constituting the second frame, and a middle plate 15.
  • FIG. 4 shows the cross section of another type of beam, consisting of rods of resistant fibers 17 coated with a polymerized synthetic resin, these rods, established in the form of bundles of parallel rods, oriented in the direction transverse, being embedded in a matrix of elastomeric material 18.
  • rods of resistant fibers 17 coated with a polymerized synthetic resin these rods, established in the form of bundles of parallel rods, oriented in the direction transverse, being embedded in a matrix of elastomeric material 18.
  • such a beam would work in traction, the ends of the rods being pinched, as indicated above.
  • connection between the fixing screw 23 ensuring rigid attachment to the other assembly, and the central part of the beam 19 it can be produced by means of a hollow metal load transfer insert, referenced in 24.
  • the desired elasticity along the axis of z can be obtained by the beam and / or by a rubber pad 25 adhered between the plate 21 and a plate 26 secured to the insert 24.
  • FIG. 7 shows a variant, according to which the desired elasticity at z can be obtained, at each end of the beam 19, by rubber washers 27 interposed between the beam and the shoulders of the inserts 20.
  • the recesses 28 of the beam 19, visible in FIG. 6, can be completely or partially filled with a damping elastomer.
